It doesn't seem like anyone has taken any lessons from 2016, to be honest. But that is okay and it doesn't matter because it's a once in a lifetime pandemic and you could probably put a box with a Che Guevara sticker up and still win against Trump right now. What does seem inevitable is that people will take the wrong lessons from 2020. I'd bet money that if a pandemic had not happened Biden would have lost.
But in any case, my postulations (and everyone else's) on an alternate election don't matter and what-ifs aren't really pertinent to right now. I just still don't think Texas is a swing state and unless I am misremembering, many others here have echoed my hesitation. I would love to be surprised, though. But like I said in my last post - I'm not particularly worried, Biden seems to have his eye on the ball and to have learned from Clinton's campaign errors.
